I find the Sig P226 to be a nicer gun than the M&P (I own both) but the DA/SA pull was something I never put the effort into learning. It would be nice if Sig could come up with a light double action only trigger variant.
My West German Sig P226 9mm is the most accurate 9mm pistol I have ever shot and reliability has never been an issue. The SP2022 I shot once was very impressive as well.
The only way I would buy another Sig is by shopping the used market. The prices they ask for new models are on the high side for what you are getting in my opinion. Wideners has used P226s for $475 right now
which seems like a good deal. The SP2022 is a steal at the $400ish price that they sell for but there is not a lot of support for them on the aftermarket side.
The M&P has proven to be a solid pistol but there have been issues with accuracy in the 9mm models. Their dependence on certain kinds of ammo to get the best performance is something that S&W needs to work on.

If this is purely because of simplicity then I can see your point but there are some good reasons to carry a gun with an exposed hammer.
One of the reasons I like an exposed hammer is because of the ability to put your thumb on the hammer when re-holstering, especially when carrying in the appendix position. It is an added level of security for me.
